To all whom it may Be itknown that I, JOHKF. OGoNnon, a" bolster and A citizen of the United States, residing in Chicage, in the county of Cook and State of Illi- 1101s, have invented a new and useful Im- Iprovement in Antiiriotion Center-Bearings 'or'Railway-Cars orother Vehicles, of which the following is a specification.

My inventlon relates to anti-friction center bearings for railway cars brother vehicles;

In anti-friction center bearings'for railwaycars of the kind great diificulty an'd'inefiicient o oration-is experienced under the enormous cad of the modernlar e heavy cars, owing tothe fact that the anti-friction rollers do notmateriall reducethe friction between the rims of the center plates under the side thrust of the tram w "en rounding curves? The object- 0f my inven strong and durable constructlon, by means of which the difficulties or objections heretofore experienced may be practically overcome without occasionirig other objections or diflioulties.

Myinvention discovered; and emplo this object or result. 'Fhat is to say, it consists' in upper and lower bearing plates provided each with a plurality of op osing or o positely inclined annular; treads and a urality of separate seriesriction *rollers travelin treads, and interposed etween the upper and lower center plates, so that the axesof one set of rollers are inwardly. and downwardly inclined, while the axes of another set ofvrollers areinwardly and-upwardly inclined, in order that the several sets of rollers consists "in the means I have on said annular 1n connection with such oppositely inclined us cause the rollers annular treads will th side thrust action of themselves to resist the I thetrain in rounding curves upon the center 111 shown and plates.

. My invention further consists in the novel construction of parts and devices and in the novel combinations of parts and. devices heredescribed.

As the inner set or series of rollers C have their axes downwardly and inwardly inclined, t eir axes oppositely inclined or inwardly and upwardly inclined, the two opposing sets of rollers C C effectually operate to resist the side thrust action of the train upon the center plates, and thus to prevent any material friction between the center lates due to the side thrust of the train, w 'le at the {same time the inner and outer sets of rollers G C in connection with the intermediate set C effectually operate to prevent material fric- MINER ooMraNr, 0F onr'oaoo,
